Introduction

NFC (near field communication) is a standards-based, short-range wireless connectivity technology that enables simple and intuitive two-way interactions between electronic devices. It is very convenient to touch and communicate between two NFC devices. For example, with smartphone-integrated NFC technology, you can easily touch your phone to purchase items, share business cards, download discount coupons and so on. You will see many NFC-based new usages will be developed in the future.
